Specific Tasks
- What are the differences in the amino acid sequences of the proteins produced by the alleles you define in Part I?
- What features of the amino acid sequence make a protein pigmented?
- What features of the amino acid sequence make a protein a particular color?
- How do the colors combine to produce an overall color? How does this explain the genotype-phenotype rules you found in part (I)?
- Which proteins are found in each of the four starting organisms?
- Using this knowledge, construct a purple protein.
